Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™. Auth0 lets you quickly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control. Authenticate users across all applications with a customized, secure, and standards-based single login. Universal Login connects users to a central authorization server. Credentials aren’t transferred across sources, which boosts security and protects against phishing and credential stuffing attacks. OAuth 2.0 recommends that only external user agents (like the browser) be used by native applications for authentication flows. Auth0’s Universal Login achieves this while enabling SSO. 1,069 Ratings Visit Website FusionAuth FusionAuth is a modern, developer-focused identity and access management platform built to give you full control over your authentication stack.

Designed with developers in mind, FusionAuth integrates seamlessly with any language, framework, or architecture. Every capability is API-first and built for extensibility, so you can tailor authentication workflows without getting locked into rigid, inflexible systems. FusionAuth supports all the key use cases — user registration, multi-factor authentication (MFA), passwordless login, role-based access control, and more — while helping you stay compliant with GDPR, HIPAA, PCI, and other regulatory standards. 191 Ratings Visit Website Securden Unified PAM Securden Unified PAM is a privileged access security solution that lets you discover, centrally store, organize, share, manage, and keep track of all privileged identities, passwords, keys, documents, and other identities.

The major modules of Securden Unified PAM are password management, privileged account management, secure remote access, application control, endpoint privilege management, privileged session management, and SSH key management. The platform supports compliance with NIS2, DORA, NIST, PCI-DSS, HIPAA, and ISO-IEC 27001.
